From the photographer: "This image features the Kepler memorial in Linz, Austria, in the light of the Full Moon. Kepler lived and worked in Linz from 1612 until 1624, longer than at any other place in his eventful life. Amongst others, he discovered the 3rd of his famous rules of planetary motion and published his work 'Harmonices Mundi libri V' during that time." - Herbert Raab
